IMPROVEMENT IN MANUFACTURE OF BUTTONS.

Specification forming part of Letters Patent No. 193,537, dated July 24,1877; application filed June 13, 1877.

To all whom it may concern:

Be it known that I, LUDovIc MILLAUX, of Waterbury, in the county of NewHaven and State of Connecticut, have in vented certain new and usefulImprovements in Button- Backs; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, which willenable others skilled in the art to which it appertains to make and usethe same.

This invention relates to certain improvements in button-backs; and theinvention consists in the peculiar construction and arrangementshereinafter more fully set forth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and arrangement.

The accompanying drawing forms a part of this specification.

The method heretofore practiced in forming button-backs is briefly setforth in the followmg:

Figure 1 represents the wire shank, which is cut in suitable lengths.Fig. 2 represents said shank provided at one end with a shoulder; Fig.3, a disk cut from sheet metal; Fig. 4, said disk struck into cup shape.Fig. 5 shows the shank and cup soldered together. Fig. 6 denotes theback disk, which is stamped from sheet metal. Fig. 7 shows the back diskand shank soldered together, also the back connected to the face orfront of the button. This is accomplished by forming a recess in theunder side of the button-face, and setting the cupped end of the shankinto said recess, then spinning or striking it down in place. Fig.S-represents the button complete.

It will be observed that seven operations are required to complete thisbutton. The

difliculty of securely connecting these parts together, and, when theback is being cohnected to the front, the liability of weakening theparts by the operation, will also be seen.

These objections I have overcome by producing a button-back made of onepiece,

pleted.

which isdescribed as follows: Fig. 9 represents the back as it comesfrom the machine. To form this back 1 take wire of the requisite sizeand length, and place one end in a solid die. The other end is, by asuitable press or stamping-machine, provided with a header having arecess or countersink of suitable form, swaged ofpressed into a disk ofthe desired shape. The recess in the end of the shank is made by asuitable punch in forcing the back out of the solid die after the diskhas been formed. To form the cup the shank is placed between two halfdies or clamps, which are provided with a recess having the upper endcountersunk to give the required shape to the cup. The recessed end ofthe shank is then spread out with a pointed or square-end punch, oranyother suitable means, as shown in Fig. 10, when the back is com- Theback is then connected to the face or front in any of the well-knownways, such as hereinbefore described, also shown in Fig. 11.

It will therefore be seen that instead of seven operations, (shown inFigs. 1, 2, 3, 4, 5, 6, and 7,) required by the old method to com pletethe button, I produce the same article, or rather a very much better andcheaper article, in three operations. (Shown in Figs. 9, 10, and 11.)

Having thus fully described my invention, what I claim as new,,anddesire to secure by Letters Patent, is

As an improvement in the manufacture of buttons, a button back and shankstruck up from a single piece of metal, one end of the shank formed witha cup shaped recess, adapted to enter the back of the face-disk of thebutton, as shown and described.

In testimony that I claim the foregoing as my own I affix my signaturein presence of two witnesses.
